METHOD OF OBTAINING OCTYLTRIETHOXYSYLANE Russian patent published in 2009 - IPC C07F7/04 C07F7/18 

FIELD: chemistry.

SUBSTANCE: method of obtaining alkylalkoxysylanes, namely octyltriethoxysylane, can be used for creating compositions, possessing water-repellent, electro-insulating and other properties, as well as intermediate product for obtaining other silicon-organic compounds. Claimed is method of obtaining octyltriethoxysylane by interaction of octane with trichlorsylane at temperature on reaction mass boiling in presence of Spier catalyst (0.1 "н" solution of platinum hydrochloric acid in isopropyl alcohol) and etherification of obtained octyltriethoxysylane with excess of absolutised alcohol with further target product separation by known methods. Invention allows to reduce time of interaction of octane with trichlorsylane (hydrosylation reaction) to 5 hours with platinum catalyst expenditure 0.0002-0.0003% of charged reagents weight, as well as eliminate application of solvent.

EFFECT: increase of hydrosylation process efficiency with minimal expenditure of platinum catalyst, reduction of reaction time and elimination of solvent application.
